Subject: [PATCH] Add a test for opening a file of a branch checked out in
 another worktree

Pressing `o` on a file in the commit files panel has the same problem as
`e` had before the previous commit. If the commit is of a branch that
another worktree has checked out, the file is still opened from the
current worktree. The absolute path in the panel's copy menu points into
the current worktree too.
